Hello,
Thanks for the query to H.C.M. Forum.
Pain is from many years and age 70 years.
Colonoscopy and C T scan five year back.
Agree five years is sufficient for a disease to spread.
You have not mentioned in your query , where is the exact site of pain?
Is burning during urination,
Constipation or
loose motion, consistency of stool?,
Is blood in urine?
is repeated urination during night time?
However pain may be due to amoebic
colitis, but without symptoms prediction is not possible.
Consult a physician /surgeon and get in complete examination and take treatment.
Hope I have answered your question.
If further any question I will help.
Good luck.
Dr. HET
